Wheat crops protection against harmful organisms using chemical treatment of seed

Abstract

In the conditions of the central area of Moldavia, losses in quantitative and qualitative wheat productions are determinated by pathogen agents which are transmitted by groundside and seed, like Fusarium sp. and Tilletia tritici, but also by some soil pests like the wire worms (Agriotes sp.) and the hunchback bug (Zabrus tenebrioides).The prevention or decreasing of the attacks was achieved in the conditions of the Agricultural Research and Development Station (ARDS) of Secuieni, Neamţ county, Romania, by the chemical treatment of the seed using a range of insectofungicides (Yunta 246 FS, Nuprid Max, Austral Plus Net, Lamardor + Gaucho, Yunta Quatrro, Yunta Succesor, Alios 300 FS). The experienced insectofungicides insured a good plant protection against the attack of Agriotes sp., the plants frequency at the untreated variant was 6.37% and between 0.77% and 1.42% at the treated variants, and against Zabrus tenebrioides species, the frequency of damaged plants at the untreated variant was 1.76%, compared

“…It is known that the entomofauna of hemp seeds can include 180-300 species (lago & Stanford, 1989;McPartland, 1996) and, depending on the geographical area, number about 20-150 specialised and polivorous phytophagous insects (McPartland et al, 2000;Trotus & Naie, 2008;Fedorenko et al, 2016), which can considerably harm the germinating seed and root system in the soil, and the aboveground vegetative and reproductive part of the plant in the herbage (Cranshaw et al, 2019;Pivtoraiko et al, 2020).…”
